Node.js Rays

Node.js & Express.js


Node.js is an open-source, server-side JavaScript runtime built on Chrome's V8 JavaScript engine. It allows developers to run JavaScript code on the server, enabling the development of scalable and high-performance web applications. Node.js provides an event-driven, non-blocking I/O model that makes it well-suited for handling concurrent requests and building real-time applications.


Express.js, often referred to as Express, is a fast and minimalist web application framework for Node.js. It provides a robust set of features and utilities for building web applications and APIs. Its simplicity, performance, and extensive ecosystem make it a popular choice for building server-side applications with Node.js.
